This publication presents good practice guidelines for the effective management and maintenance of the integrity of equipment and systems taken out of service and their related structures, on either a temporary or permanent basis, in the upstream oil and gas industry. It defines the issue and the regulatory drivers for the required industry good practice guidance and details the various equipment and systems that can be considered under a mothball approach. An extensive list of equipment and processes and their sub-systems are then considered in detail.

Based on a collation of good practice and equipment manufacturer recommended procedures, these guidelines address typical situations that are likely to arise; however, appropriate risk assessments based on contextual requirements need to be undertaken to fully determine the applicability of the outlined good practices to the specific situation.
